Vin Diesel takes some time to sit on his bike in the rain in this photo for Riddick

Over the weekend, Vin Diesel was nice enough to share a new still from RIDDICK with the fans of his Facebook page.

Why so sad Riddick? When I first saw this I wanted to put sad Keanu on the bike next to him holding a cupcake. Diesel offered up no details or anything explaining the picture. It was just his way to tell his fans to have a great weekend. I anticipate that there will be a trailer at some point soon since we've been getting quite a few pieces from this film. Diesel has always been very involved with this character and series, so I'm sure that will all come out with a trailer or possibly a clip is released.

Check out the photo below, and try not to get too sad.

Synopsis: The infamous Riddick has been left for dead on a sun-scorched planet that appears to be lifeless. Soon, however, he finds himself fighting for survival against alien predators more lethal than any human he's encountered. The only way off is for Riddick to activate an emergency beacon and alert mercenaries who rapidly descend to the planet in search of their bounty. The first ship to arrive carries a new breed of merc, more lethal and violent, while the second is captained by a man whose pursuit of Riddick is more personal. With time running out and a storm on the horizon that no one could survive, his hunters won't leave the planet without Riddick's head as their trophy.
